While it is true you can travel (one-way) from Vancouver to Tijuana on the updated Supercharger network, which offers free 20-minute recharging, returning to the nearest Supercharger outlet in Los Angeles from Tijuana would not be possible without recharging at a third-party outlet, RV park or other source, since there is Supercharger in San Diego.

L.A. to Tijuana is about 130 miles on Interstate 5 (plus a typical long wait idling at the border crossing). The Model S's maximim range with the 80 kWh battery pack is 265 miles.

Musk also said Wednesday though his Twitter account that the East Coast network connecting Montreal to Miami would be ready "in a few months."
